PB 24 01 West Essex Highlands Inc Draft Resolution

review of the Applicant’s submission and the New Jersey Stormwater Best Management Practices Manual, (“NJ BMP Manual”), there are instances where mottling can be absent from a soil profile and therefore observing mottling in a soil profile is not a requirement. Additionally, Mr. Hess noted that Chapter 12 of the NJ BMP Manual specifically outlines the methods for determining the seasonal high-water table (SHWT) when mottling is not observed. The Board’s engineer concluded that the Applicant’s Engineer’s method of determining the SHWT was consistent with the NJ BMP Manual. 57. Sean Walsh of Princeton Hydro also testified that it was his opinion that peak flow rates shown on the Applicant’s storm water testing results were not correct and that this means that there will be more run-off so there can be more flooding. 58. The Board’s expert, CME, agreed that there appeared to be some discrepancies with the groundwater mounding calculation methodology completed by the Applicant’s engineer as compared to the methodology outlined in the BMP Manual; however, the Board engineer noted that pursuant to N.J.S.A. 7:8 alternative stormwater management calculations may be used if the design engineer demonstrates to the review agency that that proposed measure and its design will contribute to the achievement of the design and performance standards established by N.J.S.A. 7:8. The Board engineer also took note of the fact that Special Condition #2 of the NJDEP Permit issued to the Applicant determined that the project met the requirements of the Stormwater Management Rules at N.J.A.C. 7:8. 59. Mr. Walsh also testified that the wetlands would be affected by the development because currently the water runoff is equal distribution, but after the development he
